NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 310,816, dated January 13, 1885.

No model.

To all whom it mtz concern:

Be it known that I, LOUIS GonDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Nailing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is an improvement on the machine represented in United States Patent No. 265,227, heretofore granted to me, to which reference may be had.

In the machine to be herein described I have provided a novel means for controlling the presentation of the loose nails to the driverpassage in the usual nose or foot, and for preventing the nails from overriding and crowding each other improperly as they are leaving the nail-holding drums. I have also provided the machine with a novel check or brake mechanism, and the nose is provided with novel arms to center the loose nails and to yield to the passage of the head of the nail as the latter is driven into the stock by the driver.

The particular features and combination of mechanical devices in which my invention consists will be specifically set forth in the claims at the end of this specification.

Figure 1 is a partial front elevation of a nailing-machine, which, in connection with the patent referred to, will enable my invention to be fully understood; Fig. 2, a righthand side elevation of Fig. 1, a portion of the nail-receiving drum having been added; Fig. 3, a detail showing the left-hand side of the movable head and theseparator; Fig. 4, an enlarged detail of the lower end of the chute, its rigid cap, the finger-carryinglever and finger to act upon the heads of the endmost nails, and the nose; Fig. 4, a section of Fig. 4 on the dotted line m",- Fig. 5,adetail showing the lower end of the chute; Fig. 6, a detail of one of the nail-centering devicesremoved. Fig. 7 isa partial top or plan view of Fig. 1, to show the devices for moving the nail-receiving drum; Fig. 8, a sectional detail of Fig. 7 in the dotted line 00 m,- Fig. 9, a detail of the fly-wheel and its check or brake device, and Fig. 10 a detail to be referred to.

The, frame-work A, movable head B, its

fork B, the shafts 0 G cam 0, wedge-block G its operating-rod O, lever 0 its operatingrod 0 gear D'-, gear D driven by it, driver a, its attached driver and awl, driver-lever 6 its operating-spring a, link 6, loose block b on shaft 0, and entering-fork B nose a, horn b edge-gage d presserb", gear (Z handle d, nail-receiving drum E, shelf h bolt h", and screw-bolts b are substantially the same in construction and operation as the parts designated by like letters in the said patent. The main shaft 0 is provided with a gear,2, which engages a larger gear, 3, which runs loosely on a stud, 4, held at its ends in brackets of the framework, the said gear 3 having attached to it a beltpulley, 6, (see Fig. 7,) which receives a belt, 7, extended over a pulley, 8, and rotates the shaft 9, to which is attached the nail-receiving drum E. The shaft 9 is extended through a sleeve-bean ing, 10, at the end of a bracket or arm, 12, suitably held in a rigid manner to the framework. The front end of the sleeve-bearing 10 is enlarged to form a chambered disk, 13, with an attached hopper, 14, the disk serving as the faceplate over and against which the rear open end of the drum rotates. The disk is notched at to receive the chute 16, having upon it the usual inclined shelf, if. The chute 16 is a slotted bar cut entirely through at its under side, between the points 17 18, Fig. 4, to permit slivers and headless or imperfect nails to drop down through the chute. The front end of the chute is attached to the head B (it being made movable so as to enable the awl connected with the driver in the saidhead to feed the stock over the usual horn) by a neck, 19, and two bolts, h and 20, so that the said chute partakes of the same movement as does the head B, or rather moves in unison with it, the chute sliding in the notches 15 in the disk 13. The chute at its lower end is inclined upward from the main top of the chute, as at 44, or is made to occupy a substantially horizontal position, to serve as a shelf or rest for the heads of one or two of the endmost nails in the groove or roadway of the said chute, substantially as in United States Patent No. 34,510, such shelf or rest permitting the body or shank of the endmost nail when its head is acted upon by a finger to be inclined or thrown away from the mass of nails in the chute, so that it may readily be picked off from the end of the chute by a sep- 5 arator, and be delivered into the driver-passage in the usual nose, 0, attached to and moving with the head B, the nose having the usual passages for both the awl and driver. The chute 16 at its rear side (see Fig. 4) has an ear, 22,which receives the bolt 23, that confines in place the rigid cover 24, V-shaped in cross-section, as shown in Fig. 4, to rest above the heads of the nails n in the chute, the top of the latter being also cut V-shaped. The upper end, 26, of the cover 24 is forked to receive between it the knocking-off wheel 27, which is acted upon by a pawl, 28, pivoted at 29 on a lug of the frame-work, and the said pawl is kept down upon the ratchet-teeth of the said wheel 27 by a spring, 30. The screw 32 serves to connect the nail-cover 24 with the chute, aad also to hold a spring, 33, which normally keeps elevated the forward end of the finger-carrying lever 34, pivoted at 35 on the rigid cover. The periphery of the wheel 27 extends into the nail receiving drum just above the nail-guiding slot in the chute, and thespace between the periphery of the said wheel and the chute is just sufficient to enable the heads of the nails which are properly placed in the chute to pass under it and out from the drum under the rigid cover. The wheel 27 mounted loosely on the pin 36, partakes of the some movement as does the chute and head B, and consequently as the chute, with the wheel 27 is moved in the direction of the arrow shown thereon in Fig. 1, the stationary pawl 28, the hook. of which engages a tooth of the said'wheel, as in Fig. 1, will cause the periphery of the wheel 27 next the top of the chute, to move in the direction of the upper end of the chute; and if the nails in the chute under the wheel 27 are properly suspended by their heads and are in proper condition to pass freely along in the chute, the pawl 28, as the chute, wheel 27, and head i B are moved in the opposite direction, retains its position on the wheel, and, being held in the base of one of the notches forming the teeth by the spring 29, the said pawl acts to slightly move the wheel 27 back into its first position. Incase the nails become clogged together under the wheel 27, the pawl 28 in engagement with it, as the chute is moved in the direction of the arrow, will turn the wheel 27 as stated, and cause its teeth next the chute to act upon and push backward the nails which are improperly lodged or thrown across the chute or which are caught between the heads of adjacent nails and rest horizontally above the chute. If the wheel 27 during this first movement fails to push back the wronglylodged nails, the latter hold and prevent the reverse swing of the wheel 27, as before re- 65 ferred to, and as the chute and head B are pivoted at 49 on the movable head B, and havmoved in the direction opposite the arrow in Fig. 1 the next tooth of the wheel 27 beyond that engaged by the pawl when the chute was moved in the direction of the'arrow referred to will pass under the pawl, and when the chute is again moved in the direction of the arrow the pawl engaging the second tooth will cause the wheel to have a quick movement, which will throw from under the wheel the improperly-lodged nails. The rotation of the wheel step by step in one direction by the pawl will continue as long as the nails under the wheel are not properly-suspended by their heads. The finger-carrying lever 34 is pro vided at its front end with a cam-roll, 38,which is acted upon by a cam, 39, fast upon the reduced end of the shaft 0, the said cam taking the place of the cam marked f in the said patent. The lever 34 has a rigid finger, 42, fastened to it by block 40 and screw 41. The lever 8 5 34 is depressed by the cam-roll 38 while the driver is being moved from its lowest to its highest point, and j ust before the separator 45 is moved to cover the end of the chute, and during this time the finger 42, attached to the lever 34, is made to descend through the slot 43 of the cover 24 and press upon the heads of the two endmost nails of the row of nails in the chute and at a point between the centers of their heads, as shown in the detail, Fig. 10, such pressure on the heads of the said nails tending to throw the point of the endmost nail toward the driver-passage in the nose 0, and the point of the nail next behind it back toward the other nails in the chute, thus leaving a clear open space for the entrance of the separator 45, forked to embrace the cars 46 of the chute 16, and attached to the separatorlever 47 by a bolt, 48, the said lever being ing a lug, 50, acted upon by a strong spring, 51, to cause the separator to close the open end of the chute 16. The lever 47 has a suitable roller-stud, 52, which is acted upon by the rear side of the cam 39 (see Fig. 3) to draw the separator from and to uncover the end of the chute, to permit the endmost nail to be delivered to the driverpassage. The nose (shown partially in section, Fig. 3) has the usual driver-passage,'55, into which enters the 1 r 5 beveled ends 56 of the-nail-centering arms 57, (see Figs. 4 and 6,) bent as shown, and having flattened ends 58, which are acted upon by a spring, 60, attached to the nose by a screw, 61, the said spring being forked or having two arms, one to bear on the arms 57 of the centering devices. The arms 57 are held in grooves 59 in the nose, and the beveled ends 56 are extended through holes 62 at the sides of the nose, and are normally kept pressed 12 5 together therein by the spring 60, so as to prevent a nail delivered into the driver-passage 55 from falling through, but permitting the said nail to be driven down between the centering devices by the driver in its descent, I 30 the said centering devices being thus forced apart, the head of the nail passing below them. When the driver a is way down, the separator 45 is drawn fully back or away from the end of the chute, and the column of nails slides down the chute until the foremost nail rests against the driver, which then acts as a stop for the said foremost nail or the one next to be driven, the driver being the only stop used when the separator is not acting to close the end of the chute 16. The foremost nail so comes against the driver during its ascent, and at such time the finger-carrying lever 34 is acted upon by the cam 39, and the finger 42 is thrown down to press upon the head of the foremost nail in the chute at that side of the center of its head toward the nail next back of it in the roadway of the chute 16. The acting face of the finger 42 is ofsueh size and shape with relation to the diameter of the heads of the nails that it acts upon the heads of the two foremost nails in such manner as to press the shank of the foremost nail toward and against the driver and the shank of the nail next to it toward the column of nails in the said roadway, thus causing the said shanks to be pressed in opposite directions or away the one from the other, in order that the separator, when moved forward by the spring 51, may have a free entrance between the shanks of the said nails. The separator enters and moves forward between the said nails as the driver ascends, and by the time that the driver passes above, the level of the head of the fore most nail the said separator also reaches such position asto force the foremost nail directly into the driver-passage under the driver, the finger 42 being lifted from the foremost nail just as the latter is to be discharged into the driver-passage. The sole-prcsser b and edge-gage d in the present instance of my invention are mounted upon a lever, 70, pivoted at 71, and provided with a roller-stud, 72,which is acted upon by a can], 73, herein shown as forming part of the gear D, such lever being used only when the machine is run by footpower, it then acting to throw down the horn. The fiy-wheel 75, fast on the shaft 0 is embraced by a flexible strap, leather, which, together with the metal brakeband 77, is riveted at one end to a block, 78,

. attached to a rigid stud, 80, provided with a roller, 79, over which the said strap 76 is passed at a point, as herein shown, beyond the outer end of the metal band 77, the said strap having a weight, 81, attached to it. The wheel may be readily turned in the direction of the arrow on it, (see Fig. 9,) but as soon as the said wheel commences to rotate in the opposite direction the band immediately checks it. This prevents the possibility of any retrograde motion of the shaft 0 and consequent slipping back of the driver before its proper time.
